Storing seed potatoes require specific conditions that can maintain their quality until the next planting season. It's essential to learn how to store seed potatoes correctly, or else they might lose germination power or attract diseases during storage. In this article, we will discuss everything you need to know about storing seed potatoes properly so that they remain healthy for growing new crops.

If you want your harvested potato seeds in good condition when it comes time for planting again, then keep reading further! We will provide all the information required on how best to store seed potatoes and avoid any issues during storage.

How to Store Seed Potatoes: A Comprehensive Guide

If you are a gardener, farmer or someone who loves growing vegetables, then you would know the importance of storing seed potatoes properly. Proper storage ensures that your seed potatoes stay healthy and viable for planting in the next season.

In this article, we will guide you on how to store seed potatoes effectively so that they remain fresh and healthy all winter long.

What Are Seed Potatoes?

Seed potatoes are small tubers that are used for planting new potato plants. They differ from regular eating potatoes as they have not been treated with any chemicals or pesticides. These tubers have sprouts on them which grow into new potato plants when planted in soil.

It is crucial to store these seeds appropriately before planting season comes around again, as it can affect their viability and health.

When Should You Store Your Seed Potatoes?

Once harvested, it's best to allow your seed potatoes a few days of 'curing' time before storing them away for the winter months. This gives time for scratches and bruises caused during harvesting to close up or heal over – reducing the risk of rot occurring while being stored away..

Curing allows excess moisture (which can cause rot) within each potato's skin cells – which often occurs during growth due to watering -to evaporate off; leaving only dry tissue behind . This prepares them well for long periods of storage by reducing opportunities available bacteria/fungi may otherwise exploit in order thrive upon bad spots/bruises etc..

After curing has taken place (usually 2-3 weeks), it’s time to start preparing your seed potates readying them up ready until spring returns!

Choosing The Right Storage Conditions

Storing your seeds at proper temperatures is important if you want good yields come harvest-time! Below we'll compare two common ways people preserve their crops:

Root Cellar:

A root cellar is an underground room that maintains a cool temperature throughout the year. It is an excellent place to store seed potatoes as it prevents them from sprouting and keeps them fresh for planting.

A root cellar should be well-ventilated to prevent excess moisture, which can cause rot, and darkness is also important as light tends to stimulate growth in spuds. The ideal temperature for storing seed potatoes in a root cellar ranges between 4°C – 7°C (38°F -45°F), with humidity levels of around 90% being most ideal.


Refrigerators offer convenience when it comes to storing food items, however they’re not always suited for preserving seeds such as potatoes!
The problem with refrigerators are that they're often too cold; causing your tubers' starches/sugars within their cells beds degrade more rapidly than desired. This often leads tubers turning bad within weeks rather than months!

If you do choose this method then make sure that you set the vegetable drawer's thermostat at temperatures no colder than approximatley 2°C (35F) degrees or higher..

How To Store Seed Potatoes

Now we'll go through some tips on how best keep your seed potatos stored:

Step One: Clean Potatoes

Before storage ensure your potato harvest is clean of all soil/dirt particles before putting away into whatever container you opt for..

This avoids unwanted bacteria/molds/fungi growth during winter time whilst waiting until planting season arises once again next spring… Also ensuring there isn't dampness left over after cleaning may be beneficial too!

Step Two: Sort By Size And Quality

After cleaning inspect each individual potato then separate out /sort by size & quality so each grouping roughly matches up like-for-like specimens..

Avoid mixing big/small fruits together if possible due differences differing textures/starch ratios present inside cell structure which may lead spoilage among weaker specimens becoming infected easier than their counterparts..

Step Three: Dry Potatoes

After sorting, let them air dry for a few days (approx 7 days) in a cool/dark location. This should ensure that any remaining moisture on the skins evaporates away.

Step Four: Packing Away

Once dried out, choose an appropriate container – e.g. paper bags, wooden crates or plastic containers- and layer your potatoes within them ensuring good ventilation is maintained.

Avoid over-packing with too many holidaymakers; as this can cause air-flow issues leading to dampness.. You want enough space between each fruit which allows optimal airflow and reduces mold growth overall!


In conclusion, storing seed potatoes doesn't have to be difficult! The key is choosing the right storage conditions such as root cellars or refrigerators at optimum temperatures/humidity levels . Secondly by selecting proper sized specimens with no damage upon inspection then drying well before prepping for storage.. Remembering that allowing enough space between each potato during packing will also prevent spoilage occurring amongst weakened tubers encourages healthy growth next season once planting time arrives again!


What are seed potatoes?

Seed potatoes are small tubers obtained from mature potato plants that have been kept in cool and dark conditions. These tubers have the potential to grow into new potato plants when planted under favorable growing conditions.

Why is it important to store seed potatoes correctly?

Storing seed potatoes correctly is crucial because it ensures that the tubers remain healthy and of good quality for planting during the next growing season. Proper storage also helps prevent diseases and pests from affecting your crops.

When should you store your seed potatoes?

You should store your seed potatoes after they have been harvested from mature potato plants, before they are planted for a new crop in the following year. You can start storing them as soon as possible after harvesting, but you need to ensure that any remaining moisture has completely evaporated before storage begins.

Where should I store my Seed Potatoes?

The ideal place to store your seed potatoes is in a dry, cool, and dark location with temperatures ranging between 4-10°C (40-50°F). This could be a basement or cellar where there's proper air circulation but no sunlight exposure or extreme temperature fluctuations. It's also advisable not to keep them near fruit or vegetables like onions which release ethylene gas – this can cause sprouting earlier than intended leading to reduced yields.

How do I prepare my Seed Potatoes for Storage?

Before storing your Seed Potatoes make sure they're well cured; this means allowing them time at room temperature (approximately 15°C/60°F) with high humidity levels of around 85% until their skin toughens up – usually two weeks post-harvesting.
Once dried thoroughly brush off any excess soil gently then inspect each one by hand removing any damaged ones along with weeds/dirt particles helping prevent bacterial growth.
It’s important not wash these since water encourages rotting thus only use damp cloth if required cleaning purposes followed by allowing them to dry naturally. Then store them into a container that can easily be covered, like a hessian bag or plastic bin but avoid using plastic bags as they do not provide adequate ventilation.

How long can seed potatoes be stored?

The length of time that seed potatoes can be stored depends on the variety of potato and how well they have been cured prior to storage. Some varieties are more perishable than others and may only last up to 6 months, while others can last up to 12 months with proper storage conditions.
It’s important regularly check your Seed Potatoes in Storage for signs of disease or decay – if any issues arise immediately remove the affected tubers so it does not infect other ones nearby. If you plan on storing these longer than six months then consider sprouting them before planting next season which entails keeping them under light at room temperature for around four weeks before planting out into soil outdoors during early springtime when conditions permit such as frost-free weather patterns.
